COCK OR FAUCET.

SPECIFICATION forming part of Letters Patent No. 769,521, dated September 6, 1904.

Application led November 5, 1903. Serial No. 179,964. (No model.)

Be it known that l, .EDWIN L. WALTnu, a citizen of the United States, residing at Scranton, in the county of Lackawanna and State of Pennsylvania, have invented certain new and useful improvements in (jocks or Faucets, of

which the following is a specification.

ln water-controlling tixturessuch as cocks, faucets, and the various types of valves--l-it is essential where economy in the consumption of water is a factor to construct the same so as to close automatically when no longer required for immediate use, thereby preventing the waste incident tot' a running stream, as when the cock is left open. Usually sel f closing` cocks require to be held open, or if provided with means to hold them open said means are either complex or are exposed to the action of the water passing' through theI cock, hence are soon impaired either by corrosive action or by sediment.

'lliis'invention aims to simplify the construction of the type of sclfclosing cocks, yet combine therewith a time mechanism and means for holding the valve open, said parts being of novel construction and arranged so as not to be in contact with or influenced by the action of the water passing through the cock. i

A further purpose of the invention is the utilization of a single spring for seating the valve and operating the movable element of the time mechanism and to devise a construction certainand positive in action, readily accessible for any purpose, not liable to get out of repair, and which will be neat, compact, reliable, and not apt to require frequent attention to maintain it in working condition.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for eifecting the result reference is to be had to the following description and drawings hereto attached.

Vhile the essential and characteristic features of the invention are susceptible of moditication, still the preferred embodiment of the invention is illustrated in the accompanying drawings, in which* Figure 1 is a vertical central section of a basin-cock embodying the invention, the valvc being closed. Fig. 2 is a View similar to Fig. 1, showing the relation of the parts when the valve is open. Fig. 3 is a view similar to Figs. 1 and 2, showing the arrangement of the parts when the piston or movable element of the time mechanism has reached a point in its return stroke to trip the catch holding the valve open. Fig. 4 isa view similar to Fig. l of a flush cock or valvc. Fig. 5 is a detail perspective view of the telescoping sections of the valve and operating stems, the parts being separated. Fig. 6 is a perspective view of the guide-sleeve. Fig. 7 is a perspective view of the catch.

(fox-responding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The body of the cock or faucet is indicated at 1 and may be of any design or finish, accoi-ding to the particular use intended and the location of the fixture. 'hen designed for lavatory purposes, the same will be provided with a spout 2; but for flushing purposes theI body will be provided with the end 3 for coupling thereto of the flush-pipe (not shown) or rubber tubing. The valve-seat 4 is located at the lower end of the body, and the valve 5 is adapted to close upward thereon and may be of any kind. A plate 6 closes the upper end of the body or casing 1 and is connected thereto in any manner, preferably by`means of the tubular section 7, threaded into the body and constituting a box to receive the packing 8, compressed by means of the gland 9, threaded into the part.7. Rims 10 and 11 project from the upper side of the plate 6 and receive the cylinder 12 and sleeve 13, which are threaded thereto. The upper end of the cylinder is closed by the cap 14, provided with the stuliing-box 15, through which th'e operating-stem 16 passes.

The valve-stem 17 is threaded to the section 18 to admit of lengthening and shortening the stem to insure proper seating of the valve. lhe section 18 has a close tit in the stuffingbox provided at the lower side of the cap 6 and is provided at its upper end with the tubular section 19, having an inner flange 20 at its upper end for coperation with'a shoulderv 21 at the lower end of the section 22, threaded to the operating-stem 16 and forming, in effeet, a part thereof. It will thus be seen that both the operating-stem and the valve-stem involve a sectional construction which have a telescopic relationthe section 22 being slidable within the section 19 The tubular section 19 is provided in a side with a slot 23 and in its upper end with a transverse slot 24 for the purpose presently to be explained.

The piston 25 is secured to the lower end of the section 16 of the operating-stem and comprises upper and lowerplates and an interposed packing 26, of rawhide or other flexible material, having its edge portion upwardly deflected. A minute passage 27 extends through the piston and is preferably formed in a plug which is passed n through corresponding openings in the component parts of the piston. The cylinder 12 below the piston is filled with any liquid, oil being preferred, and when the piston is depressed or moved downward within the cylinder the liquid passes freely by the piston, due to inward yielding' of the outer edge portion of the packing 26, and when the piston moves upward the edge portion ofthe packing 26 is pressed outward into close contact with the walls of the cylinder, thereby preventing the escape ot' the liquid thereby and compelling the same to pass through the opening 27, which of necessity requires a longer time for the piston to return to a normal position than required for its depression. The interval of time may be controlled by thesize of the opening 27 and the quantity of liquid to pass therethrough. Hence by depressing the piston to a greater or lessextent the volume of liquid passing above the same may be controlled, and this is regulated in the present instance'by means of the set-nut 28, threaded upon the upper portion of the operating-stem 16, so as to limit the downward movement of the stem by contact with the cap of the stuiing-box 15.

The valve-stem comprising the adjustable sections 1 7 and 18 is provided with the tubular section 19, with which telescopes the headed or shouldered portion of the operatingstem. A catch 29 is secured to a side of the sleeve 13 and is adapted to engage with the tubular section 19 when depressed, so as to positively hold the valve 5 unseated when the cock or ixture is open; This catch consists.l essentially, of a spring provided at its upper end with a stop 30 and a trip 31, the latter having its`lower corner beveled, as shown at 32, and of a length to project across the guidesleeve 13 and tubular section 19 and extend into the path of the head or shoulder 21 at the inner or lower end of the operating-stem when the stop 30 engages with the tubular section '19 in a manner to interlock therewith and hold the same depressed. The trip 31 extends the slot 23 of the tubular section 19. The stop 30 is beveled at its upper corner and et' greater width than the thickness of trip 31, so as to normally hold the trip 31 eut of the path of the head 21"`to admit of depressing thepiston and operating-stem when using the valve or fixture. After the operating-stem has moved a distance so as to make positive engagement with the valve-stem the latter is depressed and the valve 5 unseated, thereby permitting4 the water to ow. When the operating-stem engages positively with the valve-stem and both move together, the stop 30 comes into play to make positive engagement with the 'tubular section 19, so as to hold the valve open at the required point. In order that the valve maybe unseated to a greater or less distance, a series of notches 34 are provided in a side of the part 19 near its upper end for the stop 30 to enter, or the part 19 may be depressed, so that the stop 30 will engage over the upper end thereof. This occurs when the valve is unseated to secure a stream of maximum size. The initial movement of the operating-stem forces the piston through the liquid contained in the cylinder, and when the operating and valve stems engage, so as to move together, a continued movement of the operating-stem unseats the valve. As' the piston is moved within the cylinder a spring 35, arranged therein, is compressed, and when .the'pressure is removed from the operatingstem the spring 35 assumes anormal position and returns the parts to the original position, thereby closing the valve and resetting the working parts. The movement of the piston until the valve begins to leave its seat deter- IOO mines the time during which the cock, faucet,

or like fixture remains open, as the movement of the valve-stem is comparatively slight. To obtain a small stream, the valve is opened to a point to permit the catch toengage with the first notch of the series 34. To obtain a larger stream, the valve is opened to a greater distance to permit the catch to engage with the next notch, and so on until the maximum size of stream or flow of'water is obtained, when the catch will engage with the last notch of the series or snap over the upper end of the tubular section 19. An interval of time must .elapse after the valve has been unseated before the catch outward, thereby disengaging it from the part 19, which being released moves f upward with the operating-stem under the inuence of the spring 35, when the parts 21 and 20 engage. 4 l

To admit of the valve being unseated, in-

terlocking means are provided between the` By turning the operating-stem slightly either l to the right or to the left the stud 36 is thrown out of register with the slot 34 and in a position to engage with the upper side of the inner fiange 20. Hence a slight depression of the operating-stem unseats the valve: To return the operating-stem to a normal position, so as to bring the stud 36 in register with the slot 24, a spring 37 is provided and attached to a side of the section 22 of the operatingstem and passes through the transverse slot 211 adjacent to the vertical slot 23. Vhen the operating #stem is turned either to the right or to the left, the spring 37 is deflected from a normal position, and when the operating-stem is released the spring 37, regaining itself, turns the operating-stem and causes it to assume a normal position. This spring 37 projects from the section 22 and normally acts as a guide to hold the operating and valve stems in a given position, so as to prevent the stud 36 from getting out of line with the slot 24 under normal conditions.

I/Vhen the invention is applied to the type of cocks or like water-fixtures for use in connection with faucets and like toilet appurtenances requiring to be ushed, the spring 3T, stud 36, notches 34, and set-nut 38 may be dispensed with, and it is even contemplated within the purview of the invention under certain conditions to omit the catch, as the friction of the valve-stem and the lower stuff'- ing-box applied to the plate 6 is sufiicient to hold the valve 5 unseated during the return travel of the operating stem and piston until the shoulder 2l engages with the inner fiange 20 and causes the two parts of the stem to move in unison under the action of the spring 35, so as to seat the valve 5 and shut off' the flow of water.
